Title: Fuel cell
Inventor: TAKEUCHI SEIJI
IPC: H01M8/06
Filed: 1983-07-20
Abstract: PURPOSE:To improve the performance of a methanol fuel cell in which air is used as an oxidant by increasing the partial pressure of oxygen in the air by installing a gas-separating film on the side from which the air is supplied. CONSTITUTION:After kneaded mixture consisting of an electrode catalyst containing 15wt% of platinum, polytetrafluoroethylene used as a water repellent agent and water is applied to a carbon paper consisting of a conductive porous base member by a wet reducing method using acetylene black as the carrier, this is then sintered in air to obtain an air electrode. Current density ratios obtained by this air electrode for an air-electrode electric potential of 0.8V, as indicated by curve 4 in the figure, attained lower levels than those for an ideal curve. However, when oxygenated air containing about 35% oxygen is supplied using an oxygenated film, a current density of 75mA/cm<2> can be realized at 0.8V. This level is a great improvement as indicated by curve 3 in the figure. Polyoxyphenylene, ethyl cellulose or a similar substance can be used for the gas-separating film.

Abstract: PURPOSE:To correct the amount of expansion and contraction of an object of inspection and to execute the inspection of a pattern accurately, by a method wherein data are partially removed from or added to a binary-coded pattern data in accordance with the amount of expansion or contraction in the longitudinal or lateral direction of the measured object of the inspection. CONSTITUTION:Three CCD cameras pick up three position alignment marks on a wiring substrate, and the marks are converted into digital signals and stored in an image memory 3. A CCD one-dimensional image sensor 4 reads a wiring pattern on the substrate, and binary-coded data are delayed and sent to a storage element 7. Based on the result of calculation of the amount of expansion or contraction of an object of inspection in a control element 9, a timing pulse generating circuit 8 sends as writing pulses a pulse train obtained by removing pulses in a prescribed amount into a reference pulse train or adding them to the train periodically at a prescribed rate, so as to correct pattern data. By this method, the amount of expansion and contraction of the object of inspection is corrected and the inspection of the pattern is executed accurately.

Title: Talking control system of public telephone set
Inventor: OSADA HIROSHI
IPC: H04M17/00
Filed: 1984-06-28
Abstract: PURPOSE:To save the number of output boards of a control section by releasing the disable state of transmission depending on the response of an opposite party only at deposition of a coin when a number is dissident with a talking permissible number at the operation of an emergency switch at deposition of coin. CONSTITUTION:A control section CNT supervises a transmitted dial number and when the dial number is coincident with a talking permissible number, the disable state of transmission is released. When they are dissident and the polarity inversion of a line voltage exists due to the response of the opposite party, since the operation control of a block relay TS is executed in response to the operation of a polarity inversion relay KP only at the deposition of a coin, the talking is disabled. Thus, it is not required to provide an output board of plural bits to a dial circuit DIC and it is possible to use an inexpensive control integrated circuit of one chip configuration.

IPC: H04N7/171
Filed: 1991-05-09
Abstract: PURPOSE: To designate the polarity of video signals by providing a counter for counting specified signals during a scheduled period from the start of a field fly-back period. CONSTITUTION: A counter 21 counts line synchronization signals H and S impressed to a clock input terminal CP is the field fly-back period.
